I recently bought a truck come to find out it actually needed a new motor so I got in touch with diesel sales and ordered a OEM spec built Detroit Diesel 12.7 Id have to say for the price its worth every penny come with a great 2-year warranty you cant beat it better than the dealer for Freightliner I would highly recommend ordering your new motor from these guys they definitely know what theyre doing which is a plus in this industry next project I got is a 13 speed transmission I want and Im going to find out if they can do this if they can Ill be ordering my transmission from them

I have been purchasing container loads of engines from these guys for more than 20 years. Diesel Sales are led by profoundly serious & customer friendly people. They only sell quality engines, and the best thing is that they stand behind their product. I highly recommend Diesel Sales. I buy engines from all over the USA & Diesel Sales is one of the best engine suppliers.

I BOUGHT 9 CUMMINS ENGINES FROM THEM AND OVER HALF WERE SMOKING AND THEY WOULD NOT STAND BEHIND THE ENGINES. THEY PAWNED ME OFF ON THE ENGINE BUILDER LKQ. BUYERS BEWARE!!!!

This place is great. We have bought many engines from them and have never had a problem. Our latest purchase was for a reman QSX15 - there were some delays due to parts availability but who isnt experiencing that nowadays? They pulled some strings to get things done and it runs like a top. We are back to work and will be glad to continue our relationship. Thanks again guys!

Ordered a transmission for our 2012 these guys and received it the same day..Talk about customer service.

I bought a new engine from them, a 4TNV98 and it was smoking a lot within 6 months and I tried to file a claim of warranty and was denied. I had a 1 year warranty and they would not stand behind it. Do not buy from Dave over there, they do not tell the truth. 14 months later the engine locked up and I lost a $7500 engine. We serviced it properly, I have a shop, it was just a bad engine and a bad company to buy from.

Great company- very knowledgeable and delivered what was promised and discussed 100%. Highly recommended. Very serious business people. Thank you very much for delivering good engine and service!!!

I purchased a Reman Cat engine from Dave Gwizdalski in sales. We had a couple minor issues with this engine and I am more than impressed with the professional courtesy in which these issues were taken care of. I got full and immediate resolve without any run around. Also special kudos to Kenny Soraghan in warranty and I even got great service from Randy your shop foreman. My customer was impressed also with the quick no hassle answers to these problems. Also, I received the core refund in a very timely manner.Ive been doing this job for almost 40 years and just have to take the time to let you all know that you have a very professional team and Im going to bring as much business as I can to your company in the future. In this day and age it is refreshing to find a business that is willing to go the extra mile.RegardsDave J.

I bought a new Yanmar engine, it started smoking within 4 months, I emailed a video, called them, warned them of a problem, they didnt respond to my warranty requests, engine blew up 10 months later and they say theres no warranty. STAY AWAY from these guys! They have the worst customer service ever, they do not call you back, unless you are buying something else.

Great to do business with!

Crazy amount of inventory, they will have what you need!

Never deal with these guys. STAY AWAY!! Had me waiting for a motor for more than 3 weeks. Worst customer service ever. Just intrested in getting your money, there nothing but liers.

Great selection of Diesel engines and a quality sales staff.

Stay away from these people they get your money they dont care did not get the motor I wanted now Im stuck with something I dont want
